[rules-dev] NPE when building package

[Zoltan Farkas]

Hi Mark, I need to have the unit test inside guvnor or another project
that depends on it.
 
The code fails in guvnor when I do build package.
 
and I believe the problem might be related to BRMSPackageBuilder that
inherits from PackageBuilder or ContentPackageAssembler
 
where should I create the unit test ?

ok, can i ask you to make a unit test for me, that I can put into
MiscTest ?

Thanks

		I am getting a NPE when building a package with guvnor:

	I think it might be a bug when a package namespace doesn't have
a dot in it.

		here is my package source:
		 
		package MyTest
		import pack.EventVO
		import pack.ExtendedEventVO
		
		declare ExtendedEventVO
		    @role( event )
		end
		 
		rule "Test"
		 dialect "mvel"
		 when
		  ExtendedEventVO( )
		 then
		  System.out.println("Hello World, events happen!!!")
		end

		rule 'TestEntryPoint'
		dialect 'mvel'
		 when
		  ExtendedEventVO() from entry-point eventDoor
		 then
		  System.out.println("Hello World, events happen!!!")
		end
		 
		This seems like a possible BUG.
		 
		Let me know, thanks
